Translated from municipal
web site:
"The flag of Puerto Santander is divided in three horizontal
stripes of equal height; the upper stripe is green, meaning hope,
our fields and grasslands; the middle stripe is white, meaning
the purity of our villagers; the lower stripe is blue, identified
as the resources provided by the rivers that water the
municipality.
The flag was selected in a contest and subsequently officialized
by Municipal Decree."Ivan Sache, 15 August 2008
